<h2>Finger Tap Rates</h2>

<h3>Description</h3>

<p>Finger tap rates after drug administration
</p>


<h3>Format</h3>

<p>A data frame with 12 observations on the following 4 variables.
</p>

<dl>
<dt><code>ID</code></dt><dd><p>Case ID</p>
</dd>
<dt><code>Rate</code></dt><dd><p>Finger taps in a fixed time interval</p>
</dd>
<dt><code>Subj</code></dt><dd><p>Subject code (<code>A</code>, <code>B</code>, <code>C</code>, or <code>D</code>)</p>
</dd>
<dt><code>Drug</code></dt><dd><p>Drug administered (<code>Ca</code>=caffeine, <code>Pl</code>=placebo, or  <code>Th</code>=theobromine)</p>
</dd>
</dl>



<h3>Details</h3>

<p>Scientists Scott and Chen published research that compared the effects of caffeine with those of theobromine (a similar chemical found in chocolate) and with those of a placebo. Their experiment used four human subjects and took place over several days. Each day each subject swallowed a tablet containing one of caffeine, theobromine, or the placebo. Two hours later they were timed while tapping a finger in a specified manner (that they had practiced earlier, to control for learning effects). The response is the number
of taps in a fixed time interval.
